Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present invention clearer, the air conditioner communication fault detection method and system of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0053] In one embodiment, such as figure 1 As shown, a method for detecting an air conditioner communication fault is provided, and the method includes the following steps:

[0054] S100. Detecting a fault signal of the air conditioner when a communication failure occurs during operation of the air conditioner.

[0055] S200, judging whether the fault signal matches a preset fault signal of an external unit or a preset fault signal of an internal unit.

[0056] S210, if the failure signal matches the preset failure signal of ...

Abstract

The invention provides an air conditioner communication fault detection method and system.The method comprises the steps that when a communication fault occurs during the operating process of an air conditioner, a fault signal of the air conditioner is detected; whether the fault signal accords with a preset external unit fault signal and a preset internal unit fault signal or not is judged; if the fault signal accords with the preset external unit fault signal, it is determined that a control device of an external unit of the air conditioner breaks down; if the fault signal accords with the preset internal unit fault signal, it is determined that a control device of an internal unit of the air conditioner breaks down; if the fault signal does not accord with the preset external unit fault signal or the preset internal unit fault signal, whether a communication line is normal or not is determined according to whether signal transmission exists on the communication line or not.According to the air conditioner communication fault detection method and system, the communication fault occurrence position is accurately located according to the preset external unit fault signal and the preset internal unit fault signal, the problem that the control device of the internal unit or the external unit is replaced blindly cannot occur, convenience is brought to after-sales maintenance, and the after-sales maintenance efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an air conditioner communication fault detection method and system. Background technique [0002] Communication failure is a common failure on the inverter air conditioner. Under normal operation, the indoor and outdoor units of the inverter air conditioner perform data exchange. The communication failure is displayed on the display of the machine, and the user or after-sales maintenance personnel cannot accurately locate the communication failure. There is a problem of blindly replacing the main board of the internal unit or external unit, which brings more troubles to maintenance. Contents of the invention [0003] In view of this, it is necessary to provide an air conditioner communication fault detection method and system that can accurately locate the location of the communication fault and improve the efficiency and accuracy of after-sales maintenance for the traditiona...
